Choppy video with 4.1 in android

I am attempting to use qGroundcontrol 4.1.x with an RTSP video stream in android. I have tried both the regular version and the daily version from the play store as well as the daily apks from here:

I have tried on samsung S3 and s5e tablets. In all cases the video is very choppy (2-4 fps I would guess). Using a 4.0.x version the video shows just fine.

Has something changed that is causing the choppy video in 4.1.x? Are there any workarounds here?
